2019-12-16add little endian supportNicholas Piggin1-1/+1
This adds support for building LE skiboot with LITTLE_ENDIAN=1. This is not complete, notably PHB3, NPU* and *CAPI*, but it is sufficient to build and boot on mambo and OpenPOWER POWER9 systems. LE/ELFv2 is a nicer calling convention, and results in smaller image and less stack usage. It also follows the rest of the Linux/OpenPOWER stack moving to LE. The OPALv3 call interface still requires an ugly transition through BE for compatibility, but that is all handled on the OPAL side.

2019-12-05secvar_devtree: add generic compatible, and new format device tree propertyEric Richter1-1/+20
This patch adds a generic compatible entry to the secvar/compatible device tree property for kernels, etc to match for basic secvar information (e.g. the linux secvar-sysfs implementation). The new "format" property exposes the expected format for data passing in and out of the secvar API. In most cases, this should be the same as the backend-specific compatible entry.

These are new OPAL calls to tweak various PHB parameters. The first two are: - TVT Select 'GTE4GB' Option of the PHB control register to enable use of the second TVE for DMA trafic just above 4GB; - MMIO EEH Disable to disable EEH for all MMIO commands.

2019-08-02occ: Add pstate corresponding to base frequency to DTShilpasri G Bhat1-1/+11
Unlike POWER8, nominal frequency is not the highest guaranteed frequency of the POWER9 chip. In POWER9, the highest guaranteed frequency is greater than the nominal frequency and is referred to as base frequency. In POWER9 base frequency is the highest frequency the processor will operate at when ALL cores are active and in ANY operating condition. This patch exports the turbo pstate as the base frequency as per OCC documentation.

2019-06-04Remove POWER7 and POWER7+ supportStewart Smith1-51/+4
It's been a good long while since either OPAL POWER7 user touched a machine, and even longer since they'd have been okay using an old version rather than tracking master. There's also been no testing of OPAL on POWER7 systems for an awfully long time, so it's pretty safe to assume that it's very much bitrotted. It also saves a whole 14kb of xz compressed payload space.

2019-06-03prd: Implement generic HBRT - FSP interfaceVasant Hegde1-0/+6
This patch implements generic interface to pass data from HBRT to FSP during runtime (HBRT -> opal-prd -> kernel -> OPAL -> FSP). HBRT sends data via firmware_request interface. We have to convert that to MBOX format and send it to FSP. OPAL uses TCE mapped memory to send data. FSP will reuse same memory for response. Once processing is complete FSP sends response to OPAL. Finally OPAL calls HBRT with firmware_response message. Also introduces new opal_msg type (OPAL_MSG_PRD2) to pass bigger prd message to kernel. - if (prd_msg > OPAL_MSG_FIXED_PARAMS_SIZE) use OPAL_MSG_PRD2 Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.ibm.com>
2019-06-03opal-msg: Enhance opal-get-msg APIVasant Hegde1-3/+4
Linux uses opal_get_msg (OPAL_GET_MSG) API to get OPAL messages. This interface supports upto 8 params (64 bytes). We have a requirement to send bigger data to Linux. This patch enhances OPAL to send bigger data to Linux. - Linux will use "opal-msg-size" device tree property to allocate memory for OPAL messages (previous patch increased "opal-msg-size" to 64K). - Replaced `reserved` field in "struct opal_msg" with `size`. So that Linux side opal_get_msg user can detect actual data size. - If buffer size < actual message size, then opal_get_msg will copy partial data and return OPAL_PARTIAL to Linux. - Add new variable "extended" to "opal_msg_entry" structure to keep track of messages that has more than 64byte data. We will allocate separate memory for these messages and once kernel consumes message we will release that memory.
